How to open FWC file?

An often recurring problem with SIMATIC WinCC Project Format is that FWC is not associated with the correct program file. Thus, when you open FWC, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the FWC file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install SIMATIC WinCC

In this case, you should first verify that the SIMATIC WinCC application is installed on the computer. The easiest method is to use the system search engine by entering the program name SIMATIC WinCC in it.

Step 2. Create association of SIMATIC WinCC with FWC files

If, despite the installed application, the FWC file does not start in the SIMATIC WinCC application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the SIMATIC WinCC application as the default for handling the FWC file.

Step 3. Update SIMATIC WinCC to the latest version

If, however, after binding SIMATIC WinCC with SIMATIC WinCC Project Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Siemens AG website and install the latest version.

Step 4. Check for the following problems with the FWC file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the FWC file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our FWC file. Sometimes virus-infected FWC files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the FWC files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair FWC file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
The program can also signal the fact of encryption. The encrypted FWC files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the FWC file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file FWC to close. Some anti-virus or backup software may occupy the FWC file for a certain period of time. If nothing helps, please reset the device.
